She Wants To Kill Me With Her Love?

Three years ago I met this lady in a bus while going to work. She looked so innocent and beautiful on getting to know she told me a lot of personal things about her and her family..making me believe she was unexposed, as we continued in the relationship I discovered that she only loves me when she feels she is in need of money and once I give it to her she will turn her back and on me. She called me about a week ago asking me to change her Curve 2 to Torch which I did, just yesterday she told me she is tired of using Torch that I should get her Bold 5, I tried to talk some sense into her but she wouldn’t listen she told me I should not call or ping her until I buy the Bold 5.Please what should I do ? Should I get her the Bold5. The most painful aspect of it is that since we began dating, we have not been intimate. Should I just let her go like that?
